Implementing the Advanced Switching Fabric Discovery Process

Advanced switching is a new high-speed industrial standard serial interconnect. It is defined as a switching fabric architecture based on the PCI express technology. The advanced switching specification establishes a management infrastructure which maintains the fabric operation. The topology discovery process is triggered after fabric initialization and every time a topological change is detected. The information gathered by this process is used to build a set of paths between fabric endpoints. This work analyzes the performance of several possible implementations for this management task.
